SPLlNT-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 290,439, dated December 18, 1883.

Application tiled October 16, 1883. (No model.)

To a/ZZ whom it may concern.- l

Be it known that- I, CHARLES A. LEE, of Saginaw, in the county of Saginaw and State of Michigan, have invented new and useful Improvements in Splint-Outting Machines; and I do hereby declare that the following is a full, clear, and eXact description thereof, reference being had to the accompanying drawings, which forma part of this specification.

This invention relates to certain new and useful improvements in machines for cutting splints, whereby a bolt or block is worked or cut into splints of uniform size and length.

The invention consists in the peculiar construction and operation of a rotary cutterhead which is provided with onev or more sets of knives, each set consisting` of a knife the cutting-edge of which is placed transversely to the face of the cutter-head, and a series of other knives secured to the cutterhead in advance of the first-named knife, and with their cutting-edges parallel to the plane of motion of the cutter-head, and in the combination of the parts, as more fully hereinafter described.

Figure 1 is a plan view of the cutter-head partly in section, andshowing one set of knives. Fig. 2 is a vertical central section of the device shown in Fig. l.

` In the'accompanying drawings,which form a part of this specification, A represents a cylindrical cutter-head, of relatively large diameter, keyed upon the shaft B, which is properly journaled and provided with the driving-pulley C. The cutter-head A is cast hollow, and open at one side, as shown, and in its face are secured one or more sets of knives, D. Each set of knives consists, rst, of the knife a., which is secured in a mortise in the face of the cutter-head by means of set-screws, or in any other suitable manner. This knife a is placed tangential,or nearly so, to the face of the cutter-head, and its cuttingedge may be set either square or at a bevel with the face of the cutter-head, and it projects about one-tenth of an inch therefrom. c is a throat or passage into the hollow space of the cutter-head. E is a series of like knives secured in advance of the knife a in a mortise in the face of the cutter-head adapted to the purpose. These knives E have bevel cuttingwhich may then be secured in the mortise by means of set-screws or otherwise.

In practice this cutter-head is securely mounted upon a suitable frame-work, with bench and guides upon which to place the blocks from which the splints are to be out, and a suitable feed mechanism of any of the known constructions may be employed to feed the blocks under the cutter-head, in the rotation of which the knives may operate upon the top face of said blocks, when it will readily be seen that the knives E, which travel in advance of the knives a, produce a series of parallel cuts into the top face of the block, while the knife c following separates this por- .tion of the block from the body thereof, thereby forming a number of individual splints, which will pass through the throat c into the interior of the cutter-head, whence they are then discharged.

I do not intend to limit myself to any particular style of machine in which my cutterhead may be employed, as it will be found efficient in any machine provided with suitable feed movements.

What I claim as my invention is- In a splint-cutting machine, a revolving cutter-head provided upon its acting face with one or more sets of knives, each set consisting of a series of parallel knives, which are arranged parallel with the line of motion, and adapted to produce a series of parallel cuts of uniform depthupon the presented face of the block, and of a knife immediately following said parallel knives, constructed to shave off the partially-separated splints, substantially as and for the purposes described.

CHARLES A. LEE.
